A new team member writes a proposal using a slightly different shade of blue. Your web developer uses the wrong font on the new landing page. The print shop produces business cards that look nothing like your website because nobody sent them the right files. A social media manager posts with a graphic that doesn’t feel quite like the brand — but nobody can articulate exactly why. All of these situations share a common cause, and a common solution. The cause is the absence of a brand style guide. The solution is creating one.
